I have a couple of TI-99/4As and the RPG and adventure type games are the ones that intrigue me most.  Glad to see someone expand the library.  I have no idea how I'd play it on the real hardware (I'm sure there's a solution involving an SD card and some device I don't have), but I could emulate it. 

To play ROA on hardware, you need a SAMS, which is an expanded memory system for the TI. It's available as a PEB card or a sidecar. Another very useful device is the TIPI, which is an emulation of the entire disk system using a Raspberry PI device. It's elegant and you can transfer files from a PC over WIFI. Both of these high-demand items can be purchased from arcadeshopper.com.

Excellent, thanks for the tip!
